O'IL CUP.

Application filed October 23, 1920. Serial No. 419,036.

To all whom it may concern:

Be it known that I, GUY S. LANE, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in OilCups, of which the following is a specification.

This invention relates to oil cups.

One of the primary objects of my invention is to provide a simple andimproved automatic oiling device; and improved means for locking theparts and another of the objects of the invention consists in theprovision of means whereby a control valve mechanism of the type shownand described may be applied to an elbow cup.

The foregoing, together with such other objects as may hereinafterappear, or are incident to my invention, I obtain by means of aconstruction which I have illustrated in preferred form in theaccompanying drawings,

. wherein Fig. 1 is directed to an oil cup embodying my improvement;Fig. 2 is a plan View of a detail of my im rovement; Fig. 3 is a planview of a mo ification of such detail; Fig. 1 is a section illustratingthe application of the control valve to an elbow type of cup; and Fig. 5is a section illustrating how the oiler of Fig. 1 may be used forelbows.

Referring now to Figs. 1 and 2, the reference numeral 7 designates thecup, provided at the top with a snap lid 8 of any preferred type and atthe bottom with a hollow plug 9, the upper end of which is expanded inthe neck of the cup forming as a whole the body of the cup. The plug isexternally threaded at the bottom and is also provided with the valveseat 10. The valve stem 11 is adapted to be inserted and removed throughthe plug 9 and the inside diameter of the plug is such that the valvestem 11 may swing or oscillate partially unseating the valve to permitof seepage of oil past the valve 12. The valve is nor mally held in theposition shown in Fig. 1 by means of the spring 13, the lower end ofwhich is seated within the plug 9 and the upper end of which bearsagainst the adjustable weight 14; which has threaded engagement with theupper portion of the valve stem. The weight 14 causes the valve torespond more freely to the vibrations of the automobile or other machineto which the oil cup is applied and the degree of opening is dependentupon the position of the weight and the compression of the spring.

In order to hold the weight in any position of adjustment and at thesame time preserve ease of adjustment, I provide the followingmechanism. The weight 14.- is

formed or provided with an upstanding lip or ring-like member 15 whichis preferably integral with the weight. A portion of this lip is shearedor otherwise separated from the weight and pressed inward to provide aspring locking nose 16. By this arrangement the weight will be held inany position of adjustment and at the same time it can be readily turnedso that adjustment of the weight can be easily done. To facilitateadjustment and assembly the valve is provided with a slot 17 for thereception of a screw driver or other suitable tool.

In cases where it is desired to provide a more positive lock for theweight 14, I form a tongue 16 as shown in Fig. 3 from inspection ofwhich it will be seen that the tongue is sprung inwardly so that an edgeof the end thereof bears against the threads in such manner as to permitthe valve stem to be readily turned in the direction of the arrow butwhen it is attempted to back off the weight or to turn the valve stem inthe reverse direction, the end of the tongue will take a bite in thethread and thus positively lock the weight.

Where the tongue is formed from a member integral with the weight, Iprefer to make the weight of any material which will provide therequisite springiness for the locking tongue. I have found iron or mildsteel suitable.

Referring now to Fig. 1, it' will be noted that the plug 9' is providedwith an elbow 17, the flow of oil to which is controlled by the valve12, as before. In order to permit of the assemblage of the parts, Iprovide a boss 18 in line with the passage in the body of the plug, andI aperture and internally thread this boss for the reception of aremovable plug 19. By this arrangement the valve and valve stem can beinserted from the bottom.

If desired, instead of providing a special form of elbow cup, the formshown in Fig. 1 may be utilized by employing an elbow member 20,enlarged at 21 and internally threaded to fit the threaded end of theplug 9. The other end 22' is reduced to standard for hololing the Valvein closed position, size and externally threaded. This is an there beingan aperture for the insertion 1 V arrangement which readily permits of'asand removal of the valve, and a means for semblage and replacement. 7closing said aperture. 5 I claim: In testimony whereof, I have hereuntoIn an oil cup having an elbow, the com.- signed my name, bination of avalve for controlling the flow of oil from the oil cup to the elbow,means GUY S. LANE.
